[Therapeutic Options for Regaining Weight after Bariatric Surgery]

Area of Science:

• Bariatric surgery outcomes
• Gastroenterology
• Metabolic and endocrine disorders

Context:

• Weight regain (WR) and insufficient weight loss (IWL) are increasingly common challenges following bariatric surgery (BS).
• The rising popularity of BS necessitates effective strategies for managing post-operative weight management issues.
• Understanding the nuances of WR and IWL is crucial for patient long-term health.

Purpose:

• To provide a comprehensive overview of diagnostic and therapeutic approaches for WR and IWL after BS.
• To synthesize current literature and clinical experience to guide management decisions.
• To highlight the importance of personalized treatment strategies based on surgical history and patient factors.

Summary:

• Diagnostic evaluation is essential to identify anatomical-pathological causes or idiopathic reasons for WR/IWL.
• Surgical interventions are most effective when an anatomical-pathological cause is identified.
• For idiopathic WR/IWL, a multimodal approach combining lifestyle intervention, medication, and potentially revisional surgery is recommended.
• Specific surgical recommendations include limb lengthening/shortening for Roux-en-Y Gastric Bypass (RYGB) and considering RYGB or SADI-S for Sleeve Gastrectomy (SG) patients.

Impact:

• Informs clinical practice regarding the management of weight regain after bariatric procedures.
• Provides a framework for diagnosing and treating patients experiencing insufficient weight loss or weight regain.
• Contributes to optimizing long-term outcomes for individuals undergoing bariatric surgery.
